- you'll get ploop support (container in a single file) (this has many benefits)
- latest versions of all packages needed for openvz
- I got better general performance (e.g. less resources idle on node)

However, keeping those packages up-to-date is more complicated as you have to rerun these steps every time a new package is released.

I'm currently checking if alien builds packages are "based on the current system" or if a .deb built with alien is valid on any other machine with the same architecture/system - in that case, I'm going to try to put a repo online.
